为什么不能连接服务结构集群？

Question

我尝试使用命令连接到我刚刚通过powershell和ARM模板创建的群集（用z替换了ip号码）：

sfctl cluster select --endpoint http://z.z.z.z:19000

这是之后不久发生的错误：

＆＃13;

＆＃13;

我已阅读有关检查负载均衡器以确保其具有规则的答案。负载均衡器没有规则：

我在这里摸不着头脑，试着理解为什么它不起作用。我正在尝试创建一个部署到此服务结构群集的VSTS版本，并且正在测试它是否可用，因为我在发布中遇到错误：

##[error]No cluster endpoint is reachable, please check if there is connectivity/firewall/DNS issue.

Answer 1

您使用了错误的端口。 sfctl使用Service Fabric的HTTP API，它通常是群集上的端口19080（由负载均衡器设置屏幕截图中的LBHttpRule确认）。群集上的端口19000通常是二进制连接端口。
